Mandel, J and Sousedík, B and Šístek, J Adaptive BDDC in Three Dimensions. Math. Comput. Simulation, 82(10):1812-1831, 2012. (Unpublished)Full text not available from this repository.
The adaptive BDDC method is extended to the selection of face constraints in three dimensions. A new implementation of the BDDC method is presented based on a global formulation without an explicit coarse problem, with massive parallelism provided by a multifrontal solver. Constraints are implemented by a projection and sparsity of the projected operator is preserved by a generalized change of variables. The effectiveness of the method is illustrated on several engineering problems.
